432427 ÷ 12 
Our goal is to divide 432427 by 12.

Moving on to step 1:
If we divide 4 by 12, we get 0 and a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Bring next digit (3) of the dividend behind the 4 and repeat the process: 43 / 12

Let's proceed to step 2:
The number 12 fits into 43 3 times, leaving a remainder of 7.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtracting 36 from 43 leaves us with 7.
Bring next digit (2) of the dividend behind the 7 and repeat the process: 72 / 12

On to step 3:
When dividing 72 by 12, we get 6 with a remainder of 0.
Write down 6 as next digit of the result. 
Result so far: 36.0
Deduct 72 from 72 and we're left with 0.
Include the next digit (4) from the dividend after 0, then repeat: 4 / 12

Advancing to step 4:
When dividing 4 by 12, we get 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 360.0
If we subtract 0 from 4, we get 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 12

Advancing to step 5:
If we divide 42 by 12, we get 3 and a remainder of 6.
Record the quotient 3 as the next digit in the result. 
Result so far: 3603.0
Deduct 36 from 42 and we're left with 6.
Grab the next digit (7) from the dividend, add it to 6, then carry on: 67 / 12

Step 6:
When dividing 67 by 12, we get 5 with a remainder of 7.
Record the quotient 5 as the next digit in the result. 
Result so far: 36035.0
If we take 60 away from 67, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 7:
70 divided by 12 is 5 with a remainder of 10.
The next digit of our result is 5. 
Result so far: 36035.5
Subtracting 60 from 70 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 8:
The number 12 fits into 100 8 times, leaving a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 36035.58
If we subtract 96 from 100, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 9:
12 goes into 40 3 times with a remainder of 4.
The next digit of our result is 3. 
Result so far: 36035.583
If we take 36 away from 40, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 10:
The number 12 fits into 40 3 times, leaving a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 36035.5833
If we take 36 away from 40, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

After the division, we end up with 36035.5833 and a remainder of 4e-05.
